Abstract
A proximity detector comprising, at least one transmitter unit to transmit radiation toward a zone of interest and at least one receiver unit to receive radiation originating from the transmitter and that is reflected back from an obstacle at the zone of interest. A light-transmitter associated with each transmitter unit and a receiver light-transmitter associated with each receiver unit, a control module for controlling, processing a signal received from the receiver unit, to produce a signal responsive to the proximity of the obstacle. The light-transmitters are light-guides made of a rigid and at least translucent material.
